Embodiment Construction

[0020]Referring to FIGS. 1-4, a system 10 according to an embodiment of the invention generally includes automatically and autonomously inspecting the tires 94 on a vehicle 90, for example, for a commercial single, and tandem axle, dual wheel trailers. The system 10 includes one or more camera devices which may include a high resolution area scan camera 20, and a high-speed velocity camera 22 to photograph or capture real-time high-resolution digital images of tires of an approaching vehicle, and particularly, the treads of the vehicle's tires and sidewalls as they pass through an inspection station or through a vehicle lane 17. The images are processed at high speed to correct for geometric skewing, and then the images are analyzed to determine a tire tread depth as well as presence of any tire sidewall damage, as will be discussed in greater detail below. Results (e.g., acquired images) of the inspection are automatically forwarded, e.g., using wired or wireless communications, to...

Abstract

A system and method related thereto, for automatically inspecting at least one tire of a moving vehicle. The system includes an image acquisition device including at least one camera. The camera acquires multiple real-time images of at least one tire of a moving vehicle. As the tire of the vehicle enters a field of view of the camera, the camera component is configured to photograph and transmit the multiple photographs of the at least one tire. A light source illuminates the at least one tire of the vehicle in the field of view of the camera, and the light application may be synchronous with the imaging performed by the camera. A computer image processing component receives the multiple images transmitted from the camera and analyzes the multiple images using a detection program. The computer imaging processing component analyzing the photographs and provides an inspection analysis of each at least one tire.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority under 35 U.S.C. §119(e) of U.S. Provisional Patent Application Ser. Nos. 61 / 370,311, filed Aug. 3, 2010, and 61 / 367,698, filed Jul. 26, 2010, the disclosure of both of which are hereby incorporated by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention relates to vehicle inspections stations, and more particularly, the present invention relates to vehicle inspection stations which can automatically perform the inspection of a part of a vehicle, e.g. such as a vehicle tire, while the vehicle is in motion.BACKGROUND OF THE INVENTION[0003]Current inspection of parts of a vehicle for wear and defects is done manually for each vehicle, and by routing the vehicle to an inspection station or location. Typically, inspection of tires may be carried out by manual inspection. For example, at entry or exit to a truck or vehicle cargo loading / unloading zone or secure cargo load drop-off or pick...
